11.21 Channel Exception on Too Many Requests

Explanation: The user encounters the following error message after restarting the driver while performing transactions via MS GRAPH API.

com.novell.nds.dirxml.driver.azure.exceptions.ChannelException: {"error":{"code":"UnknownError","message":"Too Many Requests","innerError":{"date":"2023-04-03T07:39:41","request-id":"030d3573-95b1-458d-b4ef-9b6aca307d5c","client-request-id":"030d3573-95b1-458d-b4ef-9b6aca307d5c"}}}

Possible Cause:This occurs for both versions (5.1.5 and 5.1.6) of Azure AD driver due to the changes made on MS GRAPH API.

Solution: As a work around, add signInActivity attribute in “Unsupported User Attributes by MS Graph APIs” in driver configuration.
